CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of and claims priority to U.S. patentapplication Ser. No. 15/379,891, entitled “Application-Based MultipleRadio Access Technology and Platform Control Using SDN,” filed Dec. 15,2016, now allowed, which is incorporated herein by reference in itsentirety.

BACKGROUND

Mobile network traffic has been growing at a very fast pace. Inaddition, the variation of network end points, the variation ofapplications, and the variation of mobility states of user equipment(“UE”) (e.g., whether or not a UE is moving, and if so, how fast) aregrowing, and this trend will likely continue, particularly as 5Gtechnologies are deployed. 5G technologies will support divergent typesof end devices. Some of these end devices will be simple devices, suchas meter readers and other Internet of Things (“IoT”) andmachine-to-machine (“M2M”) devices, and some of these end devices willbe more complex devices, such as smartphones, that support a widevariety of applications, such as voice calling, video calling, virtualprivate networking, gaming, multimedia streaming, and the like.Moreover, the evolution to 5G networks will embrace a mosaic of radioaccess technologies (“RATs”). IoT/M2M devices also can utilize wirelineaccess for concurrent access and/or backup. While existing generalpacket radio service (“GPRS”) tunneling protocol (“GTP”) tunnel andbearer concepts may still have a role in supporting some applicationsand devices, these concepts might not be the best solution for allapplication and devices, such as IoT/M2M devices and the applicationsthese devices support. This is in part because these concepts are basedupon a connection-oriented architecture and will not scale well innetworks that adopt the aforementioned new paradigm in which billions ofIoT/M2M end points will be deployed.

SUMMARY

Concepts and technologies disclosed herein are directed toapplication-based multiple RAT (“multi-RAT”) and platform control usingSDN. According to one aspect of the concepts and technologies disclosedherein, an SDN controller can configure a radio access network (“RAN”)for connectionless services and for connection-oriented services. TheRAN can support multiple RATs, each capable of providing radio access toa device, such as a UE or an IoT device. The SDN controller candetermine a user plane path configuration for an application flowthrough at least part of the RAN. The SDN controller can provide theuser plane configuration to an SDN agent that is associated with and isenforceable by the device.

In some embodiments, the SDN controller can configure the RAN byperforming network slicing of the RAN into a first network slice thatincludes first resources to support the connectionless services. The SDNcontroller can configure the RAN by performing network slicing of theRAN into a second network slice that includes second resources tosupport the connection-oriented services.

In some embodiments, the SDN controller can determine the user planepath configuration based, at least in part, upon an overall network viewand a rule. The user plane path configuration can specify how theapplication flow should be routed through a portion of the RAN thatsupports a specific RAT of the multiple RATs. The user plane pathconfiguration also can specify how the application flow should be routedthrough the portion of the radio access network via a specific frequencyspectrum. The user plane path configuration also can specify how theapplication flow should be routed through either the first network sliceor the second network slice.

In some embodiments, the SDN controller can determine the user planepath configuration, at least in part, by negotiating with the SDN agentthat is associated with and is enforceable by the device. The SDN agentcan establish, based upon negotiations with the SDN controller, a localtable. The SDN agent can use the local table to determine how to routepackets for an application instance that utilizes the application flow.

In some embodiments, the SDN controller can provide the user plane pathconfiguration to an SDN component to configure the SDN component tosupport the application flow. The SDN controller, in some embodiments,can determine, based upon the user plane path configuration, a serviceedge configuration. The SDN controller can provide the service edgeconfiguration to a further SDN component to serve as a service edgecomponent.

In some embodiments, the SDN agent can determine how to route the packetfor the application instance that utilizes the application flow based,at least in part, upon a network condition, a device condition, or acombination thereof. The network condition, in some embodiments, can beor can include a congestion state of one or more cells provided by theRAN. The device condition, in some embodiments, can be or can include auser preference and/or a device mobility state, such as whether thedevice is moving and, if so, how fast.

In some embodiments, access can be concurrent over multiple paths. Inthese embodiments, one or more of the paths can be facilitated, at leastin part, by a wireline connection. The SDN controller's control canextend to frontend and backhaul networks for wireless and equivalentsfor wireline access. The SDN controller's control can extend similarlyat the device side of the access link(s). A single application flow canbe routed across multiple RATs and wireline in order to combinebandwidth for a single flow.

In some embodiments, the SDN controller only directs the RAN andbackhaul networks and does not involve the device, which is insteadmanipulated using protocols other than SDN. For example, if the devicehas multiple connections and possible paths for an application flow totake, SDN in the RAN can be used to drop packets along the path that theapplication should not take, and standard protocols can discover and useanother path.

DETAILED DESCRIPTION

Concepts and technologies disclosed herein are directed toapplication-based multiple RAT and platform control using SDN. Moreparticularly, the concepts and technologies disclosed herein define, atleast in part, an SDN-based framework for a per-application flow-basedintelligent routing by using enhanced SDN and Open vSwitch (“OVS”)protocols on various IP devices. The IP devices can deploy an SDNagent/client locally. The SDN agent/client can communicate with an SDNcontroller to negotiate which type of user plane path should beconfigured (i.e., a connectionless path or a connection-oriented path),what RAT would be best suited for the IP device at a given time, andwhat radio spectrum would provide the highest efficiency and benefits.Moreover, the concepts and technologies disclosed herein provide afoundation upon which to deliver application flows through an effectiveaccess network infrastructure based upon extended match-action rules,such as dynamic network policies, device mobility states, userpreferences, application preferences, some combination thereof, and/orthe like.

While the subject matter described herein may be presented, at times, inthe general context of program modules that execute in conjunction withthe execution of an operating system and application programs on acomputer system, those skilled in the art will recognize that otherimplementations may be performed in combination with other types ofprogram modules. Generally, program modules include routines, programs,components, data structures, computer-executable instructions, and/orother types of structures that perform particular tasks or implementparticular abstract data types. Moreover, those skilled in the art willappreciate that the subject matter described herein may be practicedwith other computer systems, including hand-held devices, mobiledevices, wireless devices, multiprocessor systems, distributed computingsystems, microprocessor-based or programmable consumer electronics,minicomputers, mainframe computers, routers, switches, other computingdevices described herein, and the like.

Turning now to FIG. 1, a block diagram illustrating an operatingenvironment 100 in which aspects of the concepts and technologiesdisclosed herein can be implemented. The operating environment 100includes a plurality of user equipment devices (“UEs”) 102A-102N(referred to herein collectively as UEs 102, or in the singular form asUE 102) and a plurality of IoT devices 104A-104N (referred to hereincollectively as IoT devices 104, or in the singular form as IoT device104) operating in communication with a radio access network (“RAN”) thatsupports multiple RATs (“M-RAT RAN”) 106. The UEs 102 and the IoTdevices 104 can communicate with the M-RAT RAN 106 via an air/radiointerface provided by one or more eNodeBs (“eNBs”) (not shown).

The M-RAT RAN 106 is shown as supporting both connectionless services108 and connection-oriented services 110. As used herein, a“connectionless service” is any service that allows a terminal or node(such as a UE 102, an IoT device 104, and/or other devices and systemsdisclosed herein) to send data packets to a destination withoutestablishing a connection to the destination. As also used herein, a“connection-oriented service” is any service that requires a terminal ornode (such as the UE 102 or the IoT device 104) to establish aconnection between service peers prior to any data being exchanged.

Each of the UEs 102 can be a cellular phone, a feature phone, asmartphone, a mobile computing device, a tablet computing device, aportable television, a portable video game console, or the like capableof communicating with the M-RAT RAN 106. Each of the UEs 102 can beassociated with a mobility state that specifies whether a UE 102 ismoving or not, and if so, whether the speed at which the UE 102 ismoving might be indicative of a user associated with the UE 102 walking,riding in a vehicle, or the like. The concepts and technologiesdisclosed herein can take into account device conditions, such as adevice's mobility state, as will be explained in further detail herein.Other conditions can include user preferences, for example.

Each of the IoT devices 104 can be a device that is network addressableto facilitate interconnectivity for the exchange of data. As such, theIoT devices 104 can be or can include any “thing” that is configured tobe network addressable so as to connect to and communicate with one ormore networks, such as the M-RAT RAN 106, over which to communicate withother connected devices, including, for example, the UEs 102, computers,smartphones, tablets, vehicles, other IoT devices, servers, othernetworks, the Internet, combinations thereof, and the like. Moreover,the IoT devices 104 can be deployed for consumer use, business use, andcan find application in many industry-specific use cases. For example,the IoT devices 104 may find at least partial application in thefollowing industries: automotive; energy; healthcare; industrial;retail; and smart buildings/homes. Those skilled in the art willappreciate the applicability of IoT-solutions to other industries aswell as consumer and business use cases. For this reason, applicationsof the IoT devices 104 described herein are used merely to illustratesome example applications of the IoT devices 104, and therefore shouldnot be construed as being limiting in any way. The IoT devices 104 canbenefit from a connectionless mobility architecture framework using SDNand IP protocols that provide the connectionless services 108. Thisconnectionless mobility architecture framework can eliminate the needfor complex GTP tunnels and provide a simplified mobile networkconnectivity solution to the IoT devices 104, many of which arestationary and do not require the additional functionality providedthrough the mobility architecture designed to support theconnection-oriented services 110.

The M-RAT RAN 106 can include one or more service areas (“cells”) havingthe same or different cell sizes, which may be represented by differentcell-types. As used herein, a “cell” refers to a geographical area thatis served by one or more base stations operating within an accessnetwork. The cells within the M-RAT RAN 106 can include the same ordifferent cell sizes, which may be represented by different cell-types.A cell-type can be associated with certain dimensional characteristicsthat define the effective radio range of a cell. Cell-types can include,but are not limited to, a macro cell-type, a metro cell-type, a femtocell-type, a pico cell-type, a micro cell-type, and a white spacenetwork cell-type. For ease of explanation, a “small cell” cell-type isutilized herein to collectively refer to a group of cell-types thatincludes femto cell-type, pico cell-type, and micro cell-type, ingeneral contrast to a macro cell-type, which offers a larger coveragearea. Other cell-types, including proprietary cell-types and temporarycell-types are also contemplated. The UEs 102 and the IoT devices 104are shown as being in communication with one RAN (i.e., the M-RAT RAN106), but the UEs 102 and/or the IoT devices 104 may be in communicationwith any number of access networks, including one or more non-3GPPaccess networks 112, such as a WI-FI access network. In someembodiments, the UEs 102 and/or the IoT devices 104 can be multi-modedevices, and as such, can communicate with the multiple RATs providedthrough the M-RAT RAN 106 and/or one or more RATs provided through theM-RAT RAN 106 and the non-3GPP access network 112. Moreover, in someembodiments, the IoT devices 104 can communicate with a low power widearea network (“LPWAN”) operating as part of the M-RAT RAN 106.

The M-RAT RAN 106 can operate in accordance with one or more RATs thatutilize mobile telecommunications standards including, but not limitedto, Global System for Mobile communications (“GSM”), Code DivisionMultiple Access (“CDMA”) ONE, CDMA2000, Universal MobileTelecommunications System (“UMTS”), LTE, Worldwide Interoperability forMicrowave Access (“WiMAX”), other current 3GPP cellular technologies,other future 3GPP cellular technologies, combinations thereof, and/orthe like. The M-RAT RAN 106 can utilize various channel access methods(which may or may not be used by the aforementioned standards),including, but not limited to, Time Division Multiple Access (“TDMA”),Frequency Division Multiple Access (“FDMA”), CDMA, wideband CDMA(“W-CDMA”), Orthogonal Frequency Division Multiplexing (“OFDM”),Single-Carrier FDMA (“SC-FDMA”), Space Division Multiple Access(“SDMA”), and the like to provide a radio/air interface to the UEs 102and the IoT devices 104. Data communications can be provided in part bythe M-RAT RAN 106 using General Packet Radio Service (“GPRS”), EnhancedData rates for Global Evolution (“EDGE”), the High-Speed Packet Access(“HSPA”) protocol family including High-Speed Downlink Packet Access(“HSDPA”), Enhanced Uplink (“EUL”) or otherwise termed High-Speed UplinkPacket Access (“HSUPA”), Evolved HSPA (“HSPA+”), LTE, and/or variousother current and future wireless data access technologies. Moreover,the M-RAT RAN 106 may be a GSM RAN (“GRAN”), a GSM EDGE RAN (“GERAN”), aUMTS Terrestrial Radio Access Network (“UTRAN”), an evolved U-TRAN(“E-UTRAN”), any combination thereof, and/or the like. In someembodiments, the M-RAT RAN 106 is or includes one or more virtual RANs(“vRANs”).

The non-3GPP access network 112 can include a plurality of wirelessaccess points (“APs”) (not shown). The non-3GPP access network 112 canoperate in accordance with one or more Institute of Electrical andElectronic Engineers (“IEEE”) 802.11 standards, such as, for example,IEEE 802.11a, 802.11b, 802.11g, 802.11n, 802.1ac and/or future 802.11standards (referred to herein collectively as “WI-FI”). Draft 802.11standards are also contemplated. In some implementations, the UEs 102and/or the IoT devices 104 connect to a WI-FI network via one or moresecure connections, each of which may utilize an encryption technology,such as, but not limited to, WI-FI Protected Access (“WPA”), WPA2, WiredEquivalent Privacy (“WEP”), and/or the like.

As used herein, a “base station” refers to a radio receiver and/ortransmitter (collectively, transceiver) that is/are configured toprovide a radio/air interface over which one or more of the UEs 102 andthe IoT devices 104, can connect to a network, such as the M-RAT RAN 106and/or the non-3GPP access network 112. Accordingly, a base station isintended to encompass one or more base transceiver stations (“BTSs”),one or more NBs, one or more eNBs, one or more home eNBs, one or morewireless APs, one or more multi-standard metro cell (“MSMC”) nodes,and/or other networking nodes or combinations thereof that are capableof providing a radio/air interface regardless of the technologiesutilized to do so. A base station can be in communication with one ormore antennas (not shown), each of which may be configured in accordancewith any antenna design specifications to provide a physical interfacefor receiving and transmitting radio waves to and from one or moredevices, such as the UEs 102 and the IoT devices 104.

The M-RAT RAN 106 and the non-3GPP access network 112 are shown as beingin communication with an SDN network 114. The SDN network 114 is anetwork implemented in accordance with SDN concepts. SDN is anarchitectural framework for creating intelligent networks that areprogrammable, application-aware, and more open. SDN provides an agileand cost-effective communications platform for handling the dramaticincrease in data traffic on carrier networks by providing a high degreeof scalability, security, and flexibility. SDN provides severalbenefits. SDNs can allow for the creation of multiple, virtual networkcontrol planes on common hardware. SDN can help extend servicevirtualization and software control into many existing network elements.SDN enables applications to request and manipulate services provided bythe network and allow the network to expose network states back to theapplications. SDN exposes network capabilities through applicationprogramming interfaces (“APIs”), making the control of network equipmentremotely accessible and modifiable via third-party software clients,using open protocols such as OpenFlow, available from Open Network Forum(“ONF”). 3GPP and other standards bodies and industry forums arecurrently working to standardize SDN for use in multiple aspects offuture mobile telecommunications networks under 5G standards. Anillustrative network functions virtualization platform (“NFVP”) uponwhich the SDN concepts described herein can be implanted is describedherein below with reference to FIG. 7. In addition to SDN, the conceptsand technologies disclosed herein can utilize OpenFlow vSwitch (“OVS”)to route application flows as will be described herein below.

The illustrated SDN network 114 includes an SDN controller 116. The SDNcontroller 116 can, on-demand, allocate resources to the M-RAT RAN 106.The SDN controller 116 can be configured to support any access networks,such as the M-RAT RAN 106 and the non-3GPP access network 112. The SDNcontroller 116 can support the connectionless services 108 through aconnectionless-based native IP protocol. According to embodiments, theSDN controller 116 can utilize one or more rules 118 that specify thetype of user plane path that should be configured (i.e., connectionlessvs. connection-oriented), the RAT that would be best for a given deviceat a given time, and the radio spectrum that should be utilized toprovide the most efficiency and benefits. Each of the rules 118 caninclude 5-tuples of the IP transport protocols, application instances,service requirements, active network policies, UE mobility state, userpreference, the like, or some combination thereof.

The SDN controller 116 is in communication with a plurality of SDNcomponents 120A-120N (referred to herein collectively as SDN components120, or in the singular form as SDN component 120). The SDN components120 can include one or more routers, one or more switches, one or moregateways, or some combination thereof. In some embodiments, the SDNcomponents 120 utilize OpenFlow protocols and function as OpenFlowswitches or OpenFlow routers, although the concepts and technologiesdisclosed herein are not limited to OpenFlow protocols. The SDNcomponents 120, in some embodiments, can provide, at least in part, anSDN evolved packet core (“EPC”) network. An SDN EPC network providescore network functions in accordance with 3GPP standards specificationsand implemented via the SDN network 114 using the SDN components 120 andat the control of the SDN controller 116. Accordingly, an SDN EPCnetwork can include one or more routers, one or more switches, one ormore mobility management entity (“MMEs”), one or more serving gateways(“S-GWs”), one or more packet data network gateways (“P-GWs”), one ormore combination S-GW/P-GWs, one or more home subscriber servers(“HSSs”), one or more policy and charging rules functions (“PCRFs”), oneor more DIAMETER routing agents (“DRAs”), one or more DIAMETER edgeagents (“DEAs”), one or more evolved packet data gateways (“EPDGs”), orany combination thereof. The illustrated operating environment 100 alsoincludes an EPC network 122.

The SDN components 120 can include one or more SDN MMEs. The EPC network122 also can include one or more MMEs 124. The MME(s) 124 (or SDN MME)can be configured in accordance with 3GPP standards specifications. AnMME, in general, can perform operations to control signaling trafficrelated to mobility and security for access to the M-RAT RAN 106.

The SDN components 120 can include one or more SDN S-GWs. The EPCnetwork 122 also can include one or more S-GWs 126. The S-GW(s) 126 (orSDN S-GW) can be configured in accordance with 3GPP standardsspecifications. An S-GW (or SDN S-GW) provides a point of interconnectbetween the radio-side (e.g., the M-RAT RAN 106) and an EPC network,such as an SDN EPC network created by the SDN components 120 or the EPCnetwork 122. An S-GW serves the UEs 102 and the IoT devices 104 byrouting incoming and outgoing IP packets.

The SDN components 120 can include one or more SDN P-GWs. The EPCnetwork 122 also can include one or more P-GWs 128. The P-GW 128 (or anSDN P-GW) can be configured in accordance with 3GPP standardsspecifications. A P-GW (or SDN P-GW) also interconnects an EPC network,such as an SDN EPC network created by the SDN components 120 or the EPCnetwork 122 to one or more external IP networks, such as, for example,one or more other networks 130, including other public land mobilenetworks (“PLMNs”), PDNs (e.g., the Internet), circuit-switchednetworks, and the like. A P-GW routes IP packets to and from othernetwork(s). A PGW also performs operations such as IP address/IP prefixallocation, policy control, and charging.

The SDN components 120 can include one or more HSSs. The EPC network 122also can include one or more HSSs (not shown). An HSS (or SDN HSS) canbe configured in accordance with 3GPP standards specifications. An HSSis a database that contains user-related information for users ofdevices, such as the UE 102. An HSS can provide support functions to oneor more MMES for mobility management, call and session setup, userauthentication, and access authorization.

The SDN components 120 can include one or more PCRFs. The EPC network122 also can include one or more PCRFs (not shown). A PCRF (or SDN PCRF)can be configured in accordance with 3GPP standards specifications. APCRF can determine policy rules, detect service data flows, enforcepolicies, and perform flow-based charging.

The SDN components 120 can include one or more DRAs. The EPC network 122also can include one or more DRAs (not shown). A DRA (or SDN DRA) can beconfigured in accordance with 3GPP standards specifications. A DRA is afunctional element in a 3G or 4G (e.g., LTE) network that providesreal-time routing capabilities to ensure that messages are routed amongthe correct elements within a network. DRAs were introduced by the 3GPPto address the increased DIAMETER signaling traffic and growingcomplexity of 4G LTE networks. A DRA can provide real-time routingcapabilities to ensure that DIAMETER signaling messages are routed tothe correct resources in an EPC network.

The SDN components 120 can include one or more DEAs. The EPC network 122also can include one or more DEAs (not shown). A DEA (or SDN DEA) can beconfigured in accordance with 3GPP standards specifications. A DEAprovides a point of contact into and out of an EPC core network at theDIAMETER application level. A DEA provides secure communications toconnect an EPC network to other network(s) to facilitate internetworksignaling operations (e.g., roaming, charging, and billing), forexample, between home and visited PLMN. A DEA can enable DIAMETERsignaling traffic to flow core networks while also disguising thetopology of the core networks to one another.

The SDN components 120 can include one or more SDN evolved packet datagateways (“ePDGs”). The EPC network also can include one or more EPDGs132, which interface with the P-GW 128 to provide the UEs 102 and/or theIoT devices 104 access to the EPC network 122 from untrusted non-3GPPaccess networks. The ePDG 132 functions as a security gateway to providenetwork security and interworking control via IPSec tunnel establishmentbased upon information obtained during 3GPP AAA procedures.

Returning to the UEs 102, the illustrated UE₁ 102A can store, in memory(best shown in FIG. 5), a UE AGENT₁ 136A and a UE TABLE₁ 138A; and theillustrated UE_(N) 102N can store, in memory (best shown in FIG. 5), aUE AGENT_(N) 136N and a UE TABLE_(N) 138N. The UEs 102A-102N canexecute, via one or more processors (also best shown in FIG. 5) the UEAGENTs 136A-136N to communicate with the SDN controller 116 on behalf ofthe device/user to negotiate, configure, and maintain the UE TABLES138A-138N on the UEs 102A-102N to deliver application flows through theoptimal RAT by either a connectionless or a connection-oriented userplane path. An application flow is used herein to describe thetransmission of data by a particular application executing on a UE 102or IoT DEVICE 104. In some embodiments, OVS can perform the actualrouting of the application flows to different RATs available via theM-RAT RAN 106, based upon dynamically provisioned flow delivery rulesused by the UE AGENTs 136A-136N. These rules can be the same as orsimilar to the rules 118, but specified from the perspective of the UEAGENTs 136A-136N. These rules can take into account, for example, RAT, adesired radio slice, and which user plane path (i.e., connectionless vs.connection-oriented transport services) should be utilized. The flowdelivery rules used by the UE AGENTs 136A-136N can account for othervariables. As such, the example variables noted above should not beconstrued as being limiting in any way.

Similar to the UEs 102, the illustrated IoT DEVICE₁ 104A can store, inmemory (best shown in FIG. 5), an IoT AGENT₁ 140A and an IoT TABLE₁142A; and the illustrated IoT DEVICE_(N) 104N can store, in memory (bestshown in FIG. 5), an IoT AGENT_(N) 140N and an IoT TABLE_(N) 142N. TheIoT DEVICES 104A-104N can execute, via one or more processors (also bestshown in FIG. 5) the IoT AGENTs 140A-140N to communicate with the SDNcontroller 116 on behalf of the device/user to negotiate, configure, andmaintain the IoT TABLES 142A-142N on the IoT DEVICES 104A-104N todeliver application flows through the optimal RAT by either aconnectionless or a connection-oriented application flow path. In someembodiments, OVS can perform the actual routing of the application flowsto different RATs available via the M-RAT RAN 106, based upondynamically provisioned flow delivery rules used by the IoT AGENTs140A-140N. These rules can be the same as or similar to the rules 118,but specified from the perspective of the IoT AGENTs 140A-140N. Theserules can take into account, for example, RAT, a desired radio slice,and which user plane protocol (i.e., connectionless vs.connection-oriented transport services) should be utilized. The flowdelivery rules used by the IoT AGENTs 140A-140N can account for othervariables. As such, the example variables noted above should not beconstrued as being limiting in any way.

The SDN controller 116 can configure the M-RAT RAN 106 via networkslicing to create a network slice including resources dedicated to theconnectionless services 108 and another network slice includingresources dedicated to the connection-oriented services 110. As usedherein, network slicing is an enabler for operators to optimizeperformance for both user traffic and operator network based uponapplication and service requirements on a shared network/infrastructure.Network slicing is a predominant feature of 5G network technologiessince 5G is capable of supporting services that have different networkrequirements. For example, it is possible to slice a network into aconnectionless slice on which stationary IoT devices and mobilebroadband devices operate, and to slice the network into aconnection-oriented slice on which devices that utilize voice servicesoperate.

Based upon an overall network view of the network resources availableand the rules 118, the SDN controller 116 can dynamically provide aconfiguration regarding how each application flow should be routedthrough the appropriate RAT, frequency spectrum, and network slice tothe UE AGENTs 136A-136N and/or to the IoT AGENTs 140A-140N via aprotocol such as OPENFLOW using the rules 118 to configure the UE tables138 and the IoT tables 142 (e.g., flow->radio port, frequency slice,etc.).

The SDN controller 116 can perform additional functions. For example,the SDN controller 116 can forward user plane path configurations tonetwork elements, including, for example, OpenFlow switches and routersoperating within the connectionless infrastructure. The SDN controller116 can optimize network resource allocation. The SDN controller 116 canoptionally provide service edge configurations regarding which switchand/or router should perform service edge functions for whichapplications, and how to route user packets to the service edge.

The UE AGENTs 136 and the IoT AGENTs 140 can negotiate user plane pathconfigurations with the SDN controller 116, and based upon thesenegotiations, can establish and maintain the UE tables 138 and the IoTtables 142. In addition, the UE AGENTs 136 and the IoT AGENTs 140 canmeasure network conditions (e.g., the congestion state of one or morecells of the M-RAT RAN 106) and device-related conditions (e.g., userpreference, device mobility state, and/or the like). Based upon thenetwork conditions and the device conditions, the UE AGENTs 136 and theIoT AGENTs 140 can direct application flows in accordance with the UETABLES 138 and the IoT TABLES 142, respectively.

In some embodiments, access can be concurrent over multiple paths. Inthese embodiments, one or more of the paths can be facilitated, at leastin part, by a wireline connection.

Turning now to FIG. 2, aspects of a method 200 performed by the SDNcontroller 116 for application-based multi-RAT and platform controlusing SDN concepts will be described, according to an illustrativeembodiment. It should be understood that the operations of the methodsdisclosed herein are not necessarily presented in any particular orderand that performance of some or all of the operations in an alternativeorder(s) is possible and is contemplated. The operations have beenpresented in the demonstrated order for ease of description andillustration. Operations may be added, omitted, and/or performedsimultaneously, without departing from the scope of the concepts andtechnologies disclosed herein.

It also should be understood that the illustrated methods can be endedat any time and need not be performed in their entirety. Some or alloperations of the methods, and/or substantially equivalent operations,can be performed by execution of computer-executable instructionsincluded on a computer-readable storage media, as defined below. Theterm “computer-executable instructions,” and variants thereof, as usedin the description and claims, is used expansively herein to includeroutines, application programs, software, application modules, programmodules, components, data structures, algorithms, and the like.Computer-executable instructions can be implemented on various systemconfigurations, including single-processor or multiprocessor systems,distributed computing systems, minicomputers, mainframe computers,personal computers, hand-held computing devices, microprocessor-based,programmable consumer electronics, network nodes, combinations thereof,and the like.

Thus, it should be appreciated that the logical operations describedherein may be implemented (1) as a sequence of computer implemented actsor program modules running on a computing system and/or (2) asinterconnected machine logic circuits or circuit modules within thecomputing system. The implementation is a matter of choice dependent onthe performance and other requirements of the computing system.Accordingly, the logical operations described herein are referred tovariously as states, operations, structural devices, acts, or modules.These operations, structural devices, acts, and modules may beimplemented in software, in firmware, in special purpose digital logic,and any combination thereof.

The method 200 will be described with reference to FIG. 2 and furtherreference to FIG. 1. Moreover, the operations of the method 200 will bedescribed as being performed by the SDN controller 116. These operationscan be performed via execution, by one or more processors (best shown inFIG. 4), of one or more software program modules (also best shown inFIG. 4) or applications.

The method 200 begins and proceeds to operation 202, where the SDNcontroller 116 can configure the multi-RAT RAN 106 for theconnectionless services 108 and the connection-oriented services 110 vianetwork slicing. In some embodiments, the SDN controller 116 can performnetwork slicing of the multi-RAT RAN 106 into a first network slice thatcan include first resources dedicated to providing, at least in part,the connectionless services 108. In some embodiments, the SDN controller116 can perform network slicing of the multi-RAT RAN 106 into a secondnetwork slice that can include second resources dedicated to providing,at least in part, the connection-oriented services 110.

From operation 202, the method 200 proceeds to operation 204, where theSDN controller 116 can dynamically determine a user plane pathconfiguration for each application flow through at least part of themulti-RAT RAN 106. In some embodiments, the SDN controller 116 candetermine the user plane path, at least in part, through negotiationswith SDN agents, such as one or more of the UE AGENTs 136 and/or one ormore of the IoT AGENTs 140. The SDN controller 116 can determine theuser plane path configuration for a given application flow based upon anoverall network view of the network resources available and based uponone or more of the rules 118. The SDN controller 116 can provide therule(s) 118 about what to do for given application(s). The user planepath configuration can specify how an application flow should be routedthrough at least a portion of the multi-RAT RAN 106 that supports aspecific RAT. The user plane path configuration can specify how anapplication flow should be routed through at least a portion of themulti-RAT RAN 106 that supports a specific frequency spectrum. The userplane path configuration can specify how an application flow should berouted through either the first network slice or the second networkslice.

From operation 204, the method 200 proceeds to operation 206, where theSDN controller 116 provides the user plane path configuration(s)determined at operation 204 to one or more SDN agents, such as one ormore of the UE AGENTs 136 and/or one or more of the IoT AGENTs 140. Fromoperation 206, the method 200 proceeds to operation 208, where the SDNcontroller 116 provides the user plane path configuration(s) to one ormore of the SDN components 120 to support the application flow(s). Insome embodiments, the SDN controller 116 can utilize an interface (e.g.,OPENFLOW) to configure the data plane elements, such as a switch/router,such that based on criteria (e.g., application, 5-tuple, etc.) forwardthe packets to this egress port.

From operation 208, the method 200 proceeds to operation 210, where theSDN controller 116 determines a service edge configuration to beutilized by one or more of the SDN components 120 operating at theservice edge and provides the service edge configuration to one or moreof the SDN components 120 to provide service edge functions for theconnectionless services 108 and the connection-oriented services 110.From operation 210, the method 200 proceeds to operation 212, where themethod 200 ends.

Turning now to FIG. 3, aspects of a method 300 performed by an SDNagent, such as the UE AGENT 136 or the IoT AGENT 140, forapplication-based multi-RAT and platform control using SDN concepts willbe described, according to an illustrative embodiment. The method 300will be described with reference to FIG. 3 and further reference toFIG. 1. Moreover, the operations of the method 300 will be described asbeing performed by one or more of the UEs. These operations can beperformed via execution, by one or more processors (best shown in FIG.5), of the UE AGENT 136 or the IoT AGENT 140.

The method 300 begins and proceeds to operation 302, where the SDN agentnegotiates one or more user plane path configurations with the SDNcontroller 116. The UE AGENT 136 has more knowledge about UE-specificinformation (e.g. battery status, user preference, radio networkcondition, and/or the like). Thus, even though the SDN controller 116provides general guidance about how to route the application, the UEAGENT 136 has the ability to negotiate with the SDN controller 116 andprovides feedback to the SDN controller 116 about its condition for theSDN controller 116 to provide dynamic updates on the routingconfiguration to the UE 102.

From operation 302, the method 300 proceeds to operation 304, where theSDN agent establishes the table(s)—i.e., the UE table 138 and/or the IoTtable 142. The UE table 138 and/or the IoT table 142 can includeinformation that maps specific applications to specific ports. Forexample, application A can be mapped to port X (corresponding to a radioon a connectionless slice); application B can be mapped to port Y(corresponding to another radio on a connectionless slice); andapplication C can be mapped to port Z (corresponding to a radio on aconnection-oriented slice).

From operation 304, the method 300 proceeds to operation 306, where theSDN agent measures network conditions. In some embodiments, the networkconditions can include a congestion level of the M-RAT RAN 106.

From operation 306, the method 300 proceeds to operation 308, where theSDN agent adapts the table(s) to device conditions. The deviceconditions can include, for example, a mobility state of device and/oruser preferences. For example, based on the conditions detected by thedevice, optimization can be achieved, via either communicating with theSDN controller 116 and obtaining a dynamically updated configurationrule, or the SDN controller 116 can have conditional rules (e.g., ifradio congestion state is >90%, route application to a different RAN).The SDN agent on the device can dynamically choose the radio based onthe network congestion information it receives from the radio network.

From operation 308, the method 300 proceeds to operation 310, where theSDN agent directs application flow based upon the table(s). Fromoperation 310, the method proceeds to operation 312, where the method300 ends.
